U.S. probes if Iran was behind cyberattack on utilities in Michigan, Minnesota
Malicious cyber activity affected technology at water systems in at least seven states this week, including Minnesota, leading authorities to dig into whether Iranian actors are behind the attack, CBS News has learned.
U.S. authorities are investigating whether Iran was behind a cyberattack on water systems in at least seven states, including Minnesota and Michigan. The attack forced some utilities to switch to manual operations, but all systems are operating safely. U.S. officials and sources familiar with the incident suggest the activity may be linked to Iranian hackers, but this has not been definitively attributed.
President Trump dismissed the possibility of an Iranian attack, attributing it to Minnesota's Democratic Governor, Tim Walz, who he claims is "grossly incompetent." Walz, in response, accused the Trump administration of weakening cybersecurity measures and leaving the U.S. vulnerable to cyberattacks. The FBI, EPA, and CISA have warned of attacks targeting internet-exposed industrial controllers used by water and wastewater utilities.
Minnesota's Department of Public Safety stated that no resident or customer data was accessed in the attack.
